PROBLEM TO BE SOLVED: To provide a fibrous copper fine particle fluid dispersion configured to reduce a surface resistance value change with time.SOLUTION: A fibrous copper fine particle fluid dispersion contains fibrous copper fine particles, a dispersion medium composed mainly of a protic polar solvent, and an organic compound having a triazole group. The fibrous copper fine particle fluid dispersion suppresses a reaction with dissolved oxygen or the like in a fluid dispersion, and, even when containing fibrous copper fine particles having a large surface area, is capable of sufficiently preventing deposition of impurities, such as copper oxide, on the surface of these fine particles, thereby reducing a surface resistance value change with time. 【課題】表面抵抗値の経時的な変化が抑制された繊維状銅微粒子分散液を提供する。【解決手段】繊維状銅微粒子と、プロトン性極性溶媒を主成分とする分散媒と、トリアゾール基を有する有機化合物とを含有することを特徴とする繊維状銅微粒子分散液。該繊維状銅微粒子分散液は、分散液中の溶存酸素などと反応を抑止し、表面積の大きい繊維状銅微粒子を含有しても、その表面における酸化銅などの不純物の析出を十分に防止することができるため、表面抵抗値の経時的な変化を抑制することができる。【選択図】なし
